In order to study cells taken from grey whales, a member of the team had to travel to Chukotka, an autonomous area of Russia, where annual whale hunts are regulated by the International Whaling Commission. “It was challenging to get a biopsy,” says Toren.“He had to fly there and wait for half a year.” (Para. 4)
Once the team had liver and kidney tissue from two grey whales, the researchers looked at the genes that were switched on in each sample. They sorted these “expressed” genes intocategories based on their functions, and focused on those that had previously been linked to ageing. These included those that code for proteins that affect how well the body can get rid of faultyproteins and maintain and repair DNA, as well as others involved in the workings of the immune system. (Para. 5)
